In science:

As discussed earlier, this argument cannot be invalidated by possible infra-red divergences in the perturbation theory, since we are calculating the rescaled correlation function at large wavevector.
Smectic Liquid Crystals in Random Environments
In the next section, we will show that, unsurprisingly, these lengths give the distance beyond which dislocations unbind, invalidating the purely elastic phonon theory studied in this section.
Smectic Liquid Crystals in Random Environments
We will show later that this result maybe invalidated by elastic anharmonic effects.
Smectic Liquid Crystals in Random Environments
That is, it is in principle possible that although the periodic disorder is less important than the random tilt pinning in disordering smectic layers in the elastic model, it could nevertheless drive dislocation unbinding, thereby invalidating the elastic model and the conclusions drawn from it.

Scaling and finte-size-scaling in the two dimensional random-coupling Ising ferromagnet
The tendency of the increasing ratio with t becoming sufficiently small is observed for J ′ = 0.25 and 0.1, showing that the seemingly consistency with the logarithmic correction of SSL for the larger values of t becomes invalidated in sufficiently deep scaling regime.
